Citus“ create_distributed_table”给出“ PG :: UndefinedColumn”

问题描述

当尝试使用Citus创建分布式表时,它会给出PG::UndefinedColumn: ERROR: column "x" does not exist

我在工作人员和主数据库上启用了Citus:

SELECT run_command_on_workers($cmd$
  CREATE EXTENSION citus;
$cmd$);

我创建了一个复合主键:

ActiveRecord::Base.connection.execute("
  ALTER TABLE x DROP CONSTRAINT x_pkey CASCADE;
")
ActiveRecord::Base.connection.execute("
  ALTER TABLE x ADD PRIMARY KEY (tenant_id,id);
")

尝试时:

ActiveRecord::Base.connection.execute("
SELECT create_distributed_table(x,tenant_id);
")

它一直在说:

ActiveRecord::StatementInvalid: PG::UndefinedColumn: ERROR:  column "x" does not exist
LINE 2: SELECT create_distributed_table(x,tenant_id...
                                        ^
Caused by PG::UndefinedColumn: ERROR:  column "x" does not exist

有什么我忘记的东西吗?

解决方法

表名和列名需要作为文本值传递在单引号中:SELECT create_distributed_table('x','tenant_id');
